Merging files with CR as EOL?

ruby-talk
1

i have to rewrite a script in order to be compatible with file lines
ending by CR instead of unix \n

my script is simple, it take the content of a folder and merge the file
all together in a unique file, those files have CR lines ending and such
must be the merged file.

what to do in that case ?

You could do something like

# untested
File.open("result.txt", "wb") do |out|
   Dir["*"].each do |file|
     File.open(file) do |in|
       in.each_line do |line|
         line.chomp!
         out.write(line)
         out.write("\r\n")
       end
     end
   end
end

Kind regards

If you need to work line-by-line instad of slurping them (which would be easier and line-ending agnostic), then pass CR as the optional separator to your line-oriented idiom. For example

   cr_text_file.each("\015") do |cr_line|
     # ...
   end

-- fxn
